// ChangeLine:

    // A graph's display properties (marker symbol, axis characteristics, and
    // so on) are general properties that are defined in the graph's model. The
    // line style for an interpolated line is defined as a StrokeLineStyle that
    // is applied to the plot's DataElementStyles. Thus, to change the line style,
    //    1) Get the LineChart's model
    //    2) Define a StrokeLineStyle for the plot markers
    //    3) Set the StrokeLineStyle on the model's DataElementStyles
